Penny Diffuser

I was just reading about diffuser marbles, but marbles wont fit past my ice catcher so I boiled a bunch of pennies so there nice and clean and dump them in my bong will it act like a diffuser? or is this just retarded because of using metal pennies

absolutely do NOT use copper pennies!!

a harmful gas is emitted when copper is heated

ever wonder why you never see copper pipes? =)

if you dont want to buy diffuser marbles, and are liking the loose change thing,
go with a different coin, such as a nickel

they would be much safer

you know, if you use something like nickels, you could freeze them first, in which case, they would make ultra cold hits. think about how cold metal feels when its cold. same thing.

thanks guys, I boiled some nickels clean and let them get real frosty and that shit works real niceeeeee.
